WebThiols and sulfides Learn Preparation of sulfides About this unit Alcohol and thiol groups are important functional groups for applications ranging from enzyme reactions to making flexible contact lenses. We will be reviewing naming oxygen and … Thiophenol has appreciably greater acidity than does phenol, as is shown by their pKa values (6.62 for thiophenol and 9.95 for phenol). A similar pattern is seen for H2S versus H2O, and all thiols versus the corresponding alcohols. Treatment of PhSH with strong base such as sodium hydroxide (NaOH) or sodium metal affords the salt sodium thiophenolate (PhSNa). The thiophenolate is highly nucleophilic, which translates to a high rate of alkylation. Thus, treat… physician plan florence sc
